Fndings with vasovesiculography include dilatation, mass
effect with deformity of the seminal vesicle, ejaculatory duct
stenosis, and reflux of contrast material in an ipsilateral ectopic
ureter. Connections between malformations of the seminal
tract and urinary tract may also be seen.
May display a cystic pelvic mass with a thick irregular
wall to a solid mass and apparent enlargement of the
ipsilateral seminal vesicle. Other findings could include a
well-defined low-attenuation retrovesicular mass arising
from the seminal vesicle, cephalic to the prostate gland,
with associated renal anomalies.
The multiplanar ability of MR imaging to define abdominal and pelvic
anatomy and to differentiate cystic malformations of the
pelvis make it the ideal imaging study.
usual appearance of a seminal vesicle cyst is that of cysts located
elsewhere in the body, showing low T1-weighted and high T2-weighted
signal intensity. However, seminal vesicle cysts may show
increased T1-weighted and T2-weighted signal intensity, thought
to reflect increased concentration of proteinaceous material
Surgical excision of a seminal vesicle cyst depends on the
size and location of the cyst and presence of clinical
symptoms. MR imaging may be helpful to accurately show anatomic
relationships particularly in the setting of surgical planning
for seminal vesicle cyst excision.
